My check engine light for my 96 Discovery is on and I did a test on it and it gave me these readings:
Oxygen Sensor Rich Bank B of engine, downstream of cat conv.

Engine Coolant temp sensor warm up fault.

As far as the O2 Sensor goes I'm not too familar with cars but think I can change one. Do you know where mine would be located? Also, what part number I would search for on the net to order one, because I have heard my car could have 2 or 4 of them.

As far as the Engine Coolant temp fault, do you know what this could mean? I do know that I have no air condition. In the summer I filled up the free-on and the air worked for a little while, then the free-on must have leaked out..but my car got really hot so I didnt use the air all summer and summer will be here soon so I would like to fix it before. Dont know if this also has anything to do with it, but when I'm driving down the road and I have my heater on. The heater will stop blowing out air and it will make a tick noise for a brief second and the lights will flick and the heater will come back on.

Can anyone help me? Thanks...Jeff

Coolant temp is different from HVAC.

Still learning the Rovers, but check your Coolant Temp Sensor.

The downstream 02 will be post cat convertor. Look there.
